The AirTAC Airtac SC32 Standard Cylinder SC32X70S is a genuine double-acting standard air cylinder with a Ø32mm bore and 70mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X70S is a compact double-acting tie-rod cylinder delivering 402 N of push force at 0.5 MPa (724 N at the 0.9 MPa maximum operating pressure). Its 12 mm diameter piston rod and 21 mm adjustable air cushion make it well-suited for light automation tasks where a 70 mm stroke is required.
This model carries the -S suffix, indicating a built-in magnet embedded in the piston. This allows CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for non-contact position sensing, simplifying end-of-stroke detection without external brackets or flags.

The 70 mm stroke and sensor-ready design make this cylinder ideal for ejecting lightweight plastic or metal components from a fixture, with the magnetic sensor confirming full extension before the next cycle.
Use the SC32X70S to pivot a small diverter gate on a conveyor line. The adjustable cushion reduces impact noise, and the built-in magnet provides reliable gate-position feedback to the PLC.
In benchtop lab equipment, this cylinder's 402 N push force at 0.5 MPa can sort vials or slides. The magnetic piston enables clean, non-contact position sensing in a compact footprint.
Choose the SC32 bore for light-duty clamping, sorting, or ejection where push force under 724 N is sufficient. If your load demands more force, step up to the SC40 bore which provides 628 N at 0.5 MPa. For strokes of 70 mm, the standard tie-rod design works well, but always ensure the load is guided to avoid side forces on the 12 mm rod.
When replacing an existing cylinder, match five points: 32 mm bore, 70 mm stroke, PT1/8 port thread, basic mounting (no bracket), and the -S magnet for sensor compatibility. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC32 tie-rod units.
Quick checklist
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 724 N. The theoretical maximum at 1.0 MPa is 82 kgf.
Yes. The -S suffix means a magnet is built into the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel's tie-rod slots to detect piston position without any additional mounting hardware.
